Description

Product Description

• Control and distribution unit for Dyness high-voltage battery stacks.

• Required component per battery bank to enable connection, protection, and system management functions.

• Manages stack operation including communication with compatible hybrid inverters and the integrated battery management system (BMS).

• Supports multiple battery modules stacked in series as part of a larger battery energy storage system.

• Includes fire suppression control logic that can trigger integrated suppression mechanisms if abnormal temperature is detected.

• Designed for modular and scalable high-voltage energy storage with plug-and-play stackability when paired with Dyness HV battery modules.
